Available in Coaxial (50Ω Ω and 75Ω Ω ), High-Voltage, and High-Power styles.
Cable termination and PCB mount contacts are available in right-angle and straight plugs
and receptacles.
Precision screw machine construction results in uniform contact impedance and excellent
contact retention.
Available with 30µin. or 50µin. gold contact plating.
Cable braid can be soldered or crimped.
See pages 4-55 thru 4-61 for Cinch combination layout D-subminiature connectors.
No tools are required for coaxial contact insertion. Contacts snap into connector. Coaxial and high-voltage contact
extraction tool #CET-C6B for removing contacts after termination. See page 4-103.
Tool to crimp sleeve over cable braid: Use 3-cavity die #CCD-26 with crimp frame #FCT-552. See page 4-103.
Check the style of contact required: straight or right-angle, solder braid or crimp braid, etc.
Refer to the cable wire manufacturer’s specifications to determine:
- The O.D. of the insulator.
- The O.D. of the jacket.
Compare the above with the corresponding dimensions C and E in the straight contacts and dimensions B and
C in the right-angle contacts.
